Answer 2

The difference in the appearance of aqueous solutions of nickel compounds compared to aqueous solutions of sodium compounds.is that nickel compounds are coloured and that of sodium compounds is colourless.

Explanation:

Aqueous solutions of nickel compounds:-

• Aqueous solutions of nickel compounds are green
• Nickel compounds are considered to be carcinogenic.
• It is used in the preparation of dyes.
• Nickel is known for its divalently formed compounds
• It is mainly found in oxidation number of +2

Aqueous solutions of sodium compounds:-

• Its compounds are soluble in water.
• Sodium hydroxide is considered to be ionic and aqueous compound.
• They are strongly alkaline.
• It is a colourless solution
